No worries, it's only been out for a few hours.
If it's not showing for you in your Software Update, perhaps try downloading an installer from the Apple Website at:
I think it might be worth a check with your issues. From the release notes:
iTunes 10.6.1 provides a number of improvements, including:
• Fixes several issues that may cause iTunes to unexpectedly quit while playing videos, changing artwork size in Grid view and syncing photos to devices.
• Addresses an issue where some iTunes interface elements are incorrectly described by VoiceOver and WindowEyes.
• Fixes a problem where iTunes may become unresponsive while syncing iPod nano or iPod shuffle.
• Resolves an ordering problem while browsing TV episodes in your iTunes library on Apple TV.

So, I've managed to find a slight work around. Basically, if I delete the shows from my library, but don't delete the actual files. When I add them back into my iTunes Library, they work. However, because iTunes thinks I've deleted them, in the 'Purchased' section of iTunes Store it shows that they aren't in my library, and keeps trying to redownload them.
Anybody got a better solution!?
Thanks, I had seen that option before.
I sometimes had problems though, when I open them in 32-bit mode, the sound doesn't work and I get error messages about the computer not being authorised.
I can then go back into iTunes in 64-bit and play them normally.
It's a work around, just a little annoying to have to do that when I've spent money on the items!
I was hoping for some magic fix really!!!
